真牌倒三角龙门吊本产品主梁是用矩型钢组焊成的桁架主梁结构,其横截面轮廓为倒三角形。 该主梁与传统正三角桁架相比有以下几种优势: 1、 上下弦杆截面相差不大,形心位置靠近与截面线接近,受力更加合理。 2、腹杆系统为由原来的大部分为受压杆件变成了大部分为受拉杆件,更充分利用了材料的性能。 3、腹杆采用矩形钢:传统正三角桁架用的角铁在运输或使用中遭碰撞和挤压容易变形,导致安全隐患,矩形钢抗侧向冲击力强,不易变形。 4、主梁截面是规则的三角形,可叠起来运输,运输方便。 5、制作工艺上比原来的正三角主梁焊接点和焊接量大大减少,减小了制作过程中产生的内应力危害。 6、本产品的支腿可以是钢管腿、花架腿、包厢腿,用户有很大的选择空间。 The main beam of the produ is a truss girder struure which is welded by a reangular steel group,.the cross seion of the main beam is an inverted triangle. Compared with the traditional positive triangle truss, the main girder has the following advantages: 1, on the lower chord seion difference, centroid position near the seion center line, more reasonable stress. 2, the ventral rod system on the ground for the most part of the compression bar into a majority of the tension bar, more fully utilize the material properties. 3, the traditional reangular steel truss with triangular truss are: iron in transportation.use by collision.extrusion is easy to deform.cause safety hazards, anti lateral impa force of reangular steel is strong, not easy to deformation. 4, the main beam seion is a regular triangle, can be stacked up.transport, convenient transportation. 5, the produion process than the original triangle main beam welding point.the amount of welding is greatly reduced, reducing the produion process of internal stress. 6, this produ can be leg steel legs, legs, legs flower box, users have a lot of options.
